Aderabe, using lesser known songs would be even better
Only thing that I heard that they struggled with was shoehorning songs into "themed medleys", so they limited themselves to a specific theme thereby narrowing the candidate song pool
I agree.
I think there are enough songs, but trying to find themes to connect the songs is harder. A lot of songs share the same themes as those on the first 2 albums - there are a lot of songs that could fit into the Shabbos medley, for example, that weren't included in it. So now to find a new theme connecting the songs they want to use is a lot harder, because so many central themes in songs - Golus, Achdus, Shabbos, Torah, Emunah, Mashiach, Yiddishkeit, Am Yisroel, Tefilla, Midos, Teshuva, and Yerushalayim - have been used already and are therefore out of the picture.
If anyone has ideas of a new theme with a list of songs, I'd love to hear it. The only ones I can think of would be Yamim Tovim-themed, but how many (mainly English) oldies are there about Yamim Tovim, except those on kids albums? Maybe Chanukah would have enough.
Thoughts?
